Amazon DocumentDB (with MongoDB compatibility) launches index improvements

Amazon DocumentDB launches index improvements enabling faster index builds on collections and the ability to view index build statuses. Amazon DocumentDB index builds can now be sped by up to 14X when using parallel workers compared to using a single worker. The index creation process now uses two workers by default, and you can configure the number of workers on Amazon DocumentDB 4.0 and 5.0 instance-based clusters.
